Working with INTERVAL and CURDATE in MySQL

Question

I\'m building a chart and I want to receive data for each month.

Here\'s my first request which is working:

SELECT s.GSP_nom AS nom, timestamp, AVG         


        

Answer 1

I usually use

DATE_ADD(CURDATE(), INTERVAL - 1 MONTH)

Which is almost same as Pekka's but this way you can control your INTERVAL to be negative or positive...

Answer 2

As suggested by A Star, I always use something along the lines of:

DATE(NOW()) - INTERVAL 1 MONTH

Similarly you can do:

NOW() + INTERVAL 5 MINUTE
"2013-01-01 00:00:00" + INTERVAL 10 DAY

and so on. Much easier than typing DATE_ADD or DATE_SUB all the time :)!

Answer 3

You need DATE_ADD/DATE_SUB:

AND v.date > (DATE_SUB(CURDATE(), INTERVAL 2 MONTH))
AND v.date < (DATE_SUB(CURDATE(), INTERVAL 1 MONTH))

should work.
